Question

why did liberal democratic leaders oppose the new deal?
it interfered with business and labor practices.
it led to too much government spending.
it raised taxes too much.
it did not do enough to help struggling americans.

Explanation:

Liberal Democratic leaders (in the context of the New Deal era, often more conservative - leaning Democrats or those with different ideological takes) who opposed the New Deal typically did so because they thought it didn't go far enough to assist struggling Americans. The other options: "It interfered with business and labor practices" was more of a conservative (Republican - leaning) criticism. "It led to too much government spending" was also a conservative - fiscal criticism. "It raised taxes too much" was also a fiscal - conservative type of complaint. Liberal Democratic opponents of the New Deal were more likely to think the New Deal's measures were insufficient in addressing the hardships of Americans during the Great Depression.

Answer:

It did not do enough to help struggling Americans.
